Detailed explanation-2: -The diaphragm is a dome-shaped muscle that plays a strong role in the inspiratory phase of respiration and acts as a barrier between the thoracic and abdominal cavities. The diaphragm is innervated by the phrenic nerve, which originates from the C3, C4, and C5 spinal nerve roots.
